The 2.5-million-years-old shark teeth support the theory that the capital of Yucatan may have once been underwater. A total of 15 dental fossils were found, of which 13 belong to prehistoric three different species of sharks which includes megalodon species.

Shark teeth fossil belongs to extinct species

Speleologist and photographer Kay Nicte Vilchis Zapata and her partner Erick Sosa Rodriguez were the ones who made the discovery. As per reports, the couple was diving into the sinkhole and inspecting the walls. All of a sudden they came across something peculiar, and it turned out to be ancient shark teeth. They confirmed it to be teeth of a broader category of saw shark. Reports added that an initial exam of all the dental fossils revealed they might belong to the prehistoric and extinct species of megalodon shark, mackerel shark, and saw shark. While mackerel and saw shark still exists, megalodon has become extinct.

History of Madeira

Madeira is a popular year-round resort, visited by around 1.4 million tourists every year. Owing to Madeira wine, gastronomy, historical and cultural value, flora and fauna, landscapes, the Laurel forest of Madeira was classified as UNESCO World Natural Heritage site in December 1999. The island was explored back in 75 AD by a Roman soldier named Quintus Sertorius and his army. Further, archeological evidence suggests that the islands may have been visited by the Vikings sometime between 900 and 1030. In 1419, an expedition under the captaincy of Zarco, Vaz Teixeira, and Bartolomeu Perestrello, traveled to the island to claim it on behalf of the Portuguese Crown.

In 1419, two captains of Prince Henry the Navigator, João Gonçalves Zarco, and Tristão Vaz Teixeira, were driven by a storm to the island. The next year an expedition was sent to the island to take possession on behalf of the Portuguese crown, together with captain Bartolomeu Perestrello.
